Mr. Aplin terms It,1 is known also as the " Huron.'' It almost
rivals the Skunk in the power of the odour which it can emit
when enraged. A trapped specimen was placed in a cage 50
yards or so from the house, and even at this distance it was
disagreeably easy to tell when any one visited the animal—at
least when the wind set in the right direction. It is greyish
yellow above and blackish beneath, presenting, as has been

remarked, a curious similarity to the iRatel. The nose of this
animal is destitute of a median groove, which is present in the
Tayra ; the soles of the feet, however, are naked as in that animal,
and it is nearly plantigrade in walk. It differs also from Galictis
in having sixteen 3 instead of fourteen dorsal vertebrae. Eleven
of the ribs reach the sternum. Considering the differences that
exist between. some other genera of Arctoids, it may be fairly
allowed that a genus Gh-isonia is tenable.

Gr. cdlamandi is darker coloured than the Orison, with a white
band from the forehead to the neck. Mr. T. Bell described a
tame individual as eating eggs, frogs, and even a young

A third genus of this group has recently been founded by Mr.
Oldfield Thomas 3 for a small African animal, which is Orison-like
in its coloration. The name given to the genus, Galeriscus,
is intended to suggest its likeness to the Orison (Qalera, or
Grisonid)- The chief distinctive feature of this genus, whose
skeleton is not yet known, is the presence of only four digits on
each limb ; the pollex and the hallux being entirely absent. The
ears of this Orison are short.
